Modulated Synthesis of UiO-67 for High Resistance to CH<sub>2</sub>Cl<sub>2</sub>

Abstract

UiO-67 has been synthesized by using the acetic acid as a template via conventional electric (CE) heating method. With the same adding of acetic acid, different crystallinity and pore structure are obtained through change the order of addition of acetic acid. The BET surface area and total pore volume are 2861 m2 g-1 and 1.14 cm3 g-1 for of CE-0-3, and 1650 m2 g-1 and 0.67 m2 g-1 for CE-1-2, respectively. Although CE-0-3 has a better crystallinity, higher BET surface area and total pore volume than those of CE-1-2, CE-1-2 presents a better resistance to CH2Cl2 than CE-0-3.
